Description

Technical Field

[0001] This invention relates to the field of servo motor manufacturing, and more specifically to a servo motor rotor lamination forming equipment. Background Technology

[0002] As a core drive component in industrial automation, new energy vehicles, and high-end equipment, the performance of servo motors directly depends on the manufacturing quality of their rotor cores. Rotor cores are typically made by stacking hundreds to thousands of high-grade non-oriented silicon steel sheets (usually 0.2mm-0.35mm thick). Currently, the manufacturing of servo motor rotor laminations mainly employs high-speed precision stamping technology. A typical traditional production process includes: stamping: using multi-station progressive dies to complete the blanking on a high-speed press; offline deburring: collecting and transferring the stamped laminations to a separate deburring process (such as roller grinding, vibratory finishing, belt sanding, or manual trimming); cleaning and stacking: after removing oil and residual abrasive, the laminations are neatly stacked or riveted.

[0003] As servo motors develop towards higher speeds, higher power densities, lower noise, and higher efficiency, extremely stringent requirements are placed on the dimensional accuracy, edge quality (burr height), and stacking coefficient of rotor laminations. In particular, to optimize magnetic circuit performance, modern servo motor rotor laminations are often designed with complex geometric structures, such as built-in permanent magnet slots, fine magnetic bridges, and irregularly shaped heat dissipation holes. This significantly increases the difficulty of their processing and exposes the following significant technical bottlenecks: 1. Existing stamping and deburring are usually two separate physical processes; stamping requires frequent transfer, temporary storage and secondary clamping between different equipment or workstations; this not only prolongs the production cycle and increases work-in-process inventory, but also occupies a large amount of workshop space; in addition, separate post-processing equipment increases additional energy consumption and maintenance costs. 2. During the transfer from the stamping station to the deburring station, thin silicon steel sheets are easily bumped, scratched or deformed; secondary positioning and clamping inevitably introduces cumulative errors, resulting in a decrease in the coaxiality of the stamping sheets; for high-speed rotating servo motor rotors, this small coaxiality deviation will be amplified after stacking, causing rotor dynamic balance failure, resulting in high-frequency vibration and noise during motor operation, which seriously affects product life; 3. Servo motor rotors often have deep and narrow permanent magnet slots, small magnetic bridges, and irregular heat dissipation holes. Traditional roller or vibratory grinding is a "blind grinding" process, where the abrasive has difficulty penetrating the narrow concave corners and deep slots, resulting in severe burr residue in these areas. If rigid grinding wheels or tools are used for targeted grinding, the fragile magnetic bridge structure is easily damaged due to the concentration of contact stress, and even micro-cracks may appear on the edge of the lamination, damaging the insulating coating of the silicon steel sheet and increasing the iron loss of the motor. Furthermore, offline deburring cannot ensure that every corner of every lamination is treated uniformly, often resulting in both "over-grinding" (leading to dimensional deviations and reduced stacking coefficient) and "under-grinding" (excessive burrs). In summary, existing technologies suffer from problems such as the separation of stamping and deburring processes, weak ability to handle complex irregular features, and significant loss of accuracy during secondary clamping. These issues have become key bottlenecks restricting the improvement of manufacturing quality and production efficiency of high-end servo motor rotors. Therefore, it is necessary to invent a servo motor rotor lamination processing and forming equipment. Summary of the Invention

[0014] The beneficial effects of this invention are: 1. This solution creatively integrates the deburring process into the stamping cycle (inner hole) and gravity blanking process (outer edge) through the elastic grinding and punching mechanism and the spiral floating grinding mechanism. It completely eliminates the independent offline deburring station, transfer link and secondary clamping step. Grinding is carried out by utilizing the stamping return time and gravity falling time, without occupying additional production cycle time. This allows the equipment to maintain high-speed stamping (400 SPM+) while simultaneously completing high-quality post-processing, which increases production efficiency by 30%-50%. Furthermore, since the independent grinding machine, cleaning machine and intermediate buffer area are eliminated, the floor space of the entire line is reduced by more than 60%, which significantly reduces the factory construction cost and the complexity of the logistics flow line. 2. For the complex magnetic bridge, narrow and deep permanent magnet slots and irregular heat dissipation holes unique to servo motor rotors, the "elastic sleeve radial expansion" technology is adopted to enable the abrasive layer to adaptively and tightly fit the hole wall and inner corner contour. No matter how complex the hole shape is, it can ensure that the abrasive reaches every corner, completely eliminating the "grinding dead corners" that traditional rigid tools cannot enter. 3. The spiral guide channel structure in the material stacking bin forces the stamping to spin during the falling process. Combined with the circumferentially distributed floating grinding blocks, it ensures 360° all-round uniform contact of the outer edge of the stamping. At the same time, the floating grinding blocks provide a gentle and constant contact pressure, which effectively removes burrs while avoiding magnetic bridge breakage, edge micro-cracks or damage to the insulating coating caused by over-grinding. 4. This solution requires no manual intervention or secondary positioning throughout the process, avoiding bumps and scratches during transportation and cumulative clamping errors. It ensures the coaxiality and flatness of the laminations and avoids uneven thickness caused by local over-grinding. This allows the stacking coefficient of the iron core to be increased to 0.96-0.97, effectively increasing the magnetic circuit cross-sectional area and directly improving the torque output capability and energy efficiency level of the motor.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] like Figure 1 - Figure 4 , Figure 8 , Figure 13 , Figure 15 - Figure 17 As shown, a servo motor rotor lamination processing and forming equipment includes a machine tool table 111, a lower frame 112 installed at the bottom of the machine tool table 111, a back plate 113 installed at the rear, and a first station 121, a second station 131 and a third station 141 respectively arranged from right to left on the top of the machine tool table 111. The first station 121 is equipped with a first servo electric drive base 123 at the top, and a first punch 124 is installed at the lower end of the first servo electric drive base 123. The lower end of the first punch 124 is provided with an air chamber, and a first air pressure device is connected to the air chamber at the lower end of the first punch 124. A first mounting plate 125 is installed at the lower end of the first punch 124, and a first elastic grinding and punching mechanism is installed at the bottom of the first mounting plate 125. The first elastic grinding and punching mechanism includes a first punch head 152, and a first elastic sleeve 153 is installed at the upper end of the first punch head 152. The surface of the first elastic sleeve 153 is covered with an abrasive layer. The second station 131 is equipped with a second servo electric drive base 133 at the top, and a second punch 134 is installed at the lower end of the second servo electric drive base 133. The lower end of the second punch 134 is provided with an air chamber, and a second air pressure device is connected to the air chamber at the lower end of the second punch 134. A second mounting plate 135 is installed at the lower end of the second punch 134. A second elastic grinding and punching mechanism and a third elastic grinding and punching mechanism are installed at the bottom of the second mounting plate 135. The second elastic grinding and punching mechanism includes a second punch head 162, and a second elastic sleeve 163 is installed at the upper end of the second punch head 162. The third elastic grinding and punching mechanism includes a third punch head 172, and a third elastic sleeve 173 is installed at the upper end of the third punch head 172. The surfaces of the second elastic sleeve 163 and the third elastic sleeve 173 are both covered with an abrasive layer. The third station 141 is equipped with a third servo electric drive base 143 at the top, a third punch 144 at the bottom of the third servo electric drive base 143, a third mounting plate 145 at the bottom of the third punch 144, a cutting head 146 at the bottom of the third mounting plate 145, and a material unloading stacking bin 181 at the bottom of the third station 141. The inner wall of the material unloading stacking bin 181 is provided with a spiral floating grinding mechanism, which includes a spiral guide groove 182 and several floating grinding blocks 188 evenly distributed around the inner circumference of the spiral guide groove 182.

[0019] In the above embodiments, it should be noted that this equipment needs to be used in conjunction with a hydraulic uncoiler, a multi-roller leveler, and a servo roller feeder to complete the feeding of silicon steel sheets. Specifically, the coiled silicon steel sheets are hung on the hydraulic uncoiler, the machine automatically tightens the core and releases the material at a constant speed according to the punch speed to maintain stable tension and prevent the material from loosening or breaking. The material passes through the multi-roller leveler to eliminate curling stress and wavy edges, becoming flat and straight. At the same time, the material position is automatically adjusted by the photoelectric correction device (EPC) to ensure that the strip always enters the die along the center line. The flattened material enters the servo roller feeder, which is strictly synchronized with the punch slide according to the set step distance (the distance advanced by each punch). When the punch moves downward: the rollers are released or stopped, and the material is stationary; when the punch moves upward: the rollers rotate rapidly, accurately feeding the material into the next station. The first servo drive mount 123, the second servo drive mount 133, and the third servo drive mount 143 are the core power drive units, responsible for directly controlling the vertical movement (up and down punching) of the corresponding punches. Their internal structure and working principle are the same. Figure 13 Taking the first servo electric drive base 123 as an example, by controlling the servo motor in the first servo electric drive base 123 to drive the lead screw to rotate, the first punch 124 is extended or retracted, so as to achieve the effect of controlling the first punch head 152 up and down. The first punch head 152, the second punch head 162, the third punch head 172, and the cutting head 146 all use standard high-strength alloy steel punching cutters, which are responsible for the main punching and cutting actions. The first elastic sleeve 153, the second elastic sleeve 163, and the third elastic sleeve 173 are made of ultra-thin high-strength spring steel or carbon fiber composite material, which has radial elastic deformation capability. The outer surface of the sleeve is covered with diamond micro-powder fiber or silicon carbide flexible abrasive strip through electrostatic flocking or sintering process. The particle size is customized according to the thickness of the silicon steel sheet (usually #600-#1200). The sleeve shape of the first elastic sleeve 153, the second elastic sleeve 163, and the third elastic sleeve 173 is roughly the same as that of their corresponding punch heads, which can adaptively and tightly fit the punched hole wall and inner corner contour. The floating abrasive block 188 uses polymer-bonded abrasive (such as nylon bristle mixed abrasive grains), which combines flexibility and cutting force without damaging the substrate. The spiral guide groove 182 of the material stacking bin 181 forces the punch to generate spin during the falling process. The outer edge of the rotating punch is in continuous contact with the circumferentially distributed floating abrasive blocks 188. Because the punch is rotating, every point of its outer contour (including protrusions and depressions) can pass through the abrasive block evenly, achieving 360° deburring and chamfering without dead angles. At the same time, the floating abrasive block 188 provides a gentle and constant contact pressure, which effectively removes burrs while avoiding magnetic bridge breakage, edge micro-cracks or damage to the insulating coating caused by over-grinding. This solution creatively integrates the deburring process into the stamping cycle (inner hole) and gravity blanking process (outer edge) through an elastic grinding and punching mechanism and a spiral floating grinding mechanism. It completely eliminates the separate offline deburring station, transfer link and secondary clamping step. Grinding is carried out by utilizing the stamping return time and gravity falling time, without occupying additional production cycle time. This allows the equipment to maintain high-speed stamping (400 SPM+) while simultaneously completing high-quality post-processing, which increases production efficiency by 30%-50%. Furthermore, by eliminating the separate grinding machine, cleaning machine and intermediate buffer area, the floor space of the entire line is reduced by more than 60%, which significantly reduces the factory construction cost and the complexity of the logistics flow line. Since this solution requires no manual intervention or secondary positioning throughout the process, it avoids bumps and scratches during transportation and accumulated clamping errors, ensuring the coaxiality and flatness of the laminations and preventing uneven thickness caused by local over-grinding. This allows the stacking coefficient of the iron core to be increased to 0.96-0.97, effectively increasing the magnetic circuit cross-sectional area and directly improving the torque output capability and energy efficiency level of the motor.

[0020] like Figure 1 - Figure 7 , Figure 13 and Figure 14 As shown, a servo motor rotor lamination processing and forming equipment further includes a first pneumatic device comprising a first servo air injection module 191, which is mounted on the side of a first workstation 121 via a bracket. The lower output end of the first servo air injection module 191 is connected to a first air chamber 192, and the output end of the first air chamber 192 is connected to a first air injection pipe 193. The output end of the first air injection pipe 193 is connected to the lower air chamber of a first punch rod 124. A first pneumatic valve 126 is provided on the side of the first punch rod 124, connecting to the air chamber. A first pneumatic rod 128 is slidably mounted inside the air chamber of the first punch rod 124. A piston is provided at the upper end of the first pneumatic rod 128, and its lower end penetrates through a first mounting plate 125. A first return spring 129 is installed at the bottom of the air chamber of the first punch rod 124. A first elastic grinding and punching mechanism includes a first connecting... A plurality of first connecting posts 151 are evenly distributed around the bottom of the first mounting plate 125. The lower end of the first connecting post 151 is connected to the first punch head 152. The first elastic sleeve 153 is fitted into the middle of the first connecting post 151. The first pressing head 154 is slidably installed on the upper part of the first connecting post 151. The first pressing head 154 is fixedly connected to the lower end of the first pneumatic rod 128 through a bracket. The first sliding ring 156 is slidably installed on the upper part of the first connecting post 151. The first fixing ring 155 is fixedly installed on the outer wall of the first connecting post 151 above the first sliding ring 156. The first pin 158 is slidably embedded in the inner wall of the first pressing head 154. The first floating spring 157 is installed at the embedded end of the first pin 158. The front end of the first pin 158 can abut against the first fixing ring 155 and the first sliding ring 156.

[0021] In the above embodiments, it should be noted that the first pin 158 has a downward slope on the side near the first fixing ring 155, the first fixing ring 155 has an upward slope on the side, and the first sliding ring 156 has a downward slope on the side. In the initial state, the slope of the first pin 158 abuts against the slope of the first fixing ring 155. The working principle of the first servo air injection module 191 is as follows: the servo motor in the first servo air injection module 191 drives the lead screw to rotate, which drives the internal push rod to extend into the first air chamber 192, so as to push the air in the first air chamber 192 into the lower air chamber of the first punch rod 124 along the first air injection pipe 193; conversely, the first servo air injection module 191 drives the internal push rod to push out of the first air chamber 192, which can draw the air in the lower air chamber of the first punch rod 124 into the first air chamber 192. At this time, the first air pressure valve 126 is used to balance the internal and external air pressure. The first station's workflow (single stroke cycle): When the silicon steel sheet is fed into the first station 121, the first servo electric drive base 123 controls the first punch rod 124 to drive the first mounting plate 125 and the connected first punch head 152 downwards. The first punch head 152 punches the silicon steel sheet. At this time, the first elastic sleeve 153 is in a contracted state (diameter slightly smaller than the hole diameter) and passes through the silicon steel sheet without interference. The moment the first elastic sleeve 153 penetrates the silicon steel sheet, the first servo air injection module 191 is activated to push the air in the first air chamber 192 along the first air injection... The air chamber at the lower end of the first punch rod 124 is injected through pipe 193. The air pressure inside the chamber rises, pushing the first pneumatic rod 128 in conjunction with the first pressing head 154 to move downward. This triggers the first pin 158 to retract and move downward to between the first fixed ring 155 and the first sliding ring 156. The first fixed ring 155 mechanically limits the first pin 158. As the first pressing head 154 moves downward, it forces the first elastic sleeve 153 to expand radially and uniformly (expansion amount approximately 0.02-0.05 mm), making the abrasive layer tightly adhere to the hole wall and inner corner. Then, the first servo electric drive base 12... 3. Control the first punch rod 124 to drive the first mounting plate 125 and the connected first punch head 152 to move upwards and back. The first elastic sleeve 153 remains in an expanded state, using the upward friction force to perform unidirectional scraping and grinding on the hole wall, effectively removing burrs from the fracture zone and repairing micro-cracks. When the first elastic sleeve 153 is completely disengaged from the hole, the first servo air injection module 191 is activated again to push the air in the first air chamber 192 into the lower air chamber of the first punch rod 124 along the first air injection pipe 193. The air pressure in the air chamber of the first pin 158 rises, pushing the first pneumatic rod 1 28. The first pressing head 154 moves downward, triggering the first pin 158 to retract and move downward to below the first sliding ring 156. The first return spring 129 pushes the first pneumatic rod 128 to move the first pressing head 154 upward. The first pin 158 drives the first sliding ring 156 to slide upward and contact the first fixed ring 155. Then, the first pin 158 retracts and moves upward along the inclined plane to above the first fixed ring 155, releasing the mechanical limit on the first pressing head 154. The first pressing head 154 resets, and the first elastic sleeve 153 retracts, preparing for the next cycle.

[0022] like Figure 1 - Figure 3 and Figure 8 - Figure 12As shown, a servo motor rotor lamination forming equipment further includes a second pneumatic device comprising a second servo air injection module 194. The second servo air injection module 194 is mounted on the side of the second workstation 131 via a bracket. The lower output end of the second servo air injection module 194 is connected to a second air chamber 195. The output end of the second air chamber 195 is connected to a second air injection pipe 196. The output end of the second air injection pipe 196 is connected to the lower air chamber of a second punch rod 134. A second pneumatic valve 136 is provided on the side of the second punch rod 134, which is connected to the air chamber. A second pneumatic rod 138 is slidably installed inside the air chamber of the second punch rod 134. A piston is installed at the upper end of the second pneumatic rod 138, and its lower end penetrates through the second mounting plate 135. A second return spring 139 is installed at the bottom of the air chamber of the second punch rod 134. The second elastic grinding and punching mechanism includes a second connecting post 161. Several second connecting posts 161 are evenly distributed around the bottom of the second mounting plate 135. The lower end of the second connecting post 161 is connected to the second punch head 162. A second elastic sleeve 163 is fitted into the middle of the second connecting post 161. A second pressing head 164 is slidably installed on the upper part of the second connecting post 161. The second pressing head 164 is fixedly connected to the lower end of the second pneumatic rod 138 through a bracket. A second sliding ring 166 is slidably mounted on the upper part. A second fixed ring 165 is fixedly mounted on the outer wall of the second connecting post 161 above the second sliding ring 166. A second pin 168 is slidably embedded in the inner wall of the second pressing head 164. A second floating spring 167 is installed at the embedded end of the second pin 168. The front end of the second pin 168 can abut against the second fixed ring 165 and the second sliding ring 166. The third elastic grinding and punching mechanism includes a third connecting post 171. Several third connecting posts 171 are evenly distributed around the bottom center of the second mounting plate 135. The lower end of the third connecting post 171 is connected to the third punching head 172. The third spring... The sleeve 173 is fitted into the middle of the third connecting post 171. A third pressing head 174 is slidably installed on the upper part of the third connecting post 171. The third pressing head 174 is fixedly connected to the lower end of the second pneumatic rod 138. A third sliding ring 176 is slidably installed on the upper part of the third connecting post 171. A third fixing ring 175 is fixedly installed on the outer wall of the third connecting post 171 above the third sliding ring 176. A third pin 178 is slidably embedded in the inner wall of the third pressing head 174. A third floating spring 177 is installed at the embedded end of the third pin 178. The front end of the third pin 178 can abut against the third fixing ring 175 and the third sliding ring 176.

[0023] In the above embodiments, it should be noted that the second pin 168 has a downward slope on the side near the second fixing ring 165, the second fixing ring 165 has an upward slope on the side, and the second sliding ring 166 has a downward slope on the side. In the initial state, the slope of the second pin 168 abuts against the slope of the second fixing ring 165. The structure and position of the third pin 178, the third fixing ring 175, and the third sliding ring 176 are the same as those of the second pin 168. The working principle of the second servo air injection module 194 is as follows: the servo motor in the second servo air injection module 194 drives the lead screw to rotate, which drives the internal push rod to extend into the second air chamber 195, so as to push the air in the second air chamber 195 into the lower air chamber of the second punch 134 along the second air injection pipe 196; conversely, the second servo air injection module 194 drives the internal push rod to exit the second air chamber 195, which can draw the air in the lower air chamber of the second punch 134 into the second air chamber 195. At this time, the second air pressure valve 136 is used to balance the internal and external air pressure. Second station workflow (single stroke cycle): When the silicon steel sheet is fed into the second station 131, the second servo electric drive base 133 controls the second punch rod 134 to drive the second mounting plate 135 and the connected second punch head 162 and third punch head 172 downwards. The second punch head 162 and third punch head 172 punch the silicon steel sheet. At this time, the second elastic sleeve 163 and third elastic sleeve 173 are in a contracted state (diameter slightly smaller than the hole diameter) and pass through the silicon steel sheet without interference. When the second elastic sleeve 163 and third elastic sleeve 173 penetrate the silicon steel sheet, the second servo air injection module 194 is activated to push the air in the second air chamber 195 into the lower air chamber of the second punch rod 134 along the second air injection pipe 196. The air pressure in the air chamber rises and pushes the second punch rod 134 downwards. The pneumatic rod 138, in conjunction with the second and third pressing heads 164 and 174, moves downward, triggering the second pin 168 to retract and descend between the second fixed ring 165 and the second sliding ring 166. The third pin 178 retracts and descends between the third fixed ring 175 and the third sliding ring 176. The second fixed ring 165 and the third fixed ring 175 mechanically limit the second pin 168 and the third pin 178, respectively. As the second and third pressing heads 164 and 174 move downward, they force the second and third elastic sleeves 163 and 173 to expand radially and uniformly (expansion amount approximately 0.02-0.05 mm), ensuring the abrasive layer tightly adheres to the hole wall and inner corners. Then, the second servo air injection module 194 controls the second punch 134 to... During the upward return stroke of the mounting plate 135 and the connected second punch head 162 and third punch head 172, the second elastic sleeve 163 and third elastic sleeve 173 remain in an expanded state. Utilizing upward friction, they perform unidirectional scraping and polishing of the hole wall, effectively removing burrs from the fracture zone and repairing micro-cracks. When the second elastic sleeve 163 and third elastic sleeve 173 are completely disengaged from the hole, the second servo air injection module 194 is activated again, pushing air from the second air chamber 195 into the lower air chamber of the second punch rod 134 along the second air injection pipe 196. The increased air pressure in the air chamber pushes the second pneumatic rod 138, in conjunction with the second and third downward pressure heads 164 and 174, downward. This triggers the second pin 168 to retract and descend to below the second sliding ring 166, and the third pin 178 retracts and descends. When the second return spring 139 reaches below the third sliding ring 176, it pushes the second pneumatic rod 138 to move the second pressing head 164 and the third pressing head 174 upward. The second pin 168 drives the third sliding ring 176 to slide upward and contact the second fixed ring 165. The third pin 178 then drives the second sliding ring 166 to slide upward and contact the third fixed ring 175. Afterward, the second pin 168 retracts and moves upward along the inclined plane to above the second fixed ring 165, and the third pin 178 retracts and moves upward along the inclined plane to above the third fixed ring 175, releasing the mechanical limit on the second pressing head 164 and the third pressing head 174. The second pressing head 164 and the third pressing head 174 reset, and the second elastic sleeve 163 and the third elastic sleeve 173 retract, preparing for the next cycle.

[0024] like Figure 1 - Figure 3 and Figure 16 - Figure 19 As shown, a servo motor rotor lamination forming equipment further includes a plurality of grooves evenly distributed around the inner circumference of a blanking stacking bin 181. A fourth floating spring 189 is installed in the grooves of the inner wall of the blanking stacking bin 181. The rear end of a floating grinding block 188 is inserted into the groove of the inner wall of the blanking stacking bin 181. A base 186 is installed at the bottom of the blanking stacking bin 181. The base 186 is mounted on a lower frame 112. A discharge port 187 is provided on the front of the base 186. 87 connects to the lower outlet of the material stacking bin 181. The top of the material stacking bin 181 is provided with an air outlet gap 185. The air outlet gap 185 connects to the upper end of the spiral guide channel 182 and the outside of the material stacking bin 181. An air inlet channel 184 is provided on the lower side of the material stacking bin 181. The air inlet channel 184 connects to the lower end of the spiral guide channel 182. An air pump 183 is installed on the outer wall of the material stacking bin 181. The output end of the air pump 183 is connected to the input end of the air inlet channel 184.

[0025] In the above embodiments, it should be noted that when the silicon steel sheet is fed into the third station 141, the third servo electric drive base 143 controls the third punch rod 144 to drive the third mounting plate 145 and the connected punching head 146 to move downward. The punching head 146 punches the silicon steel sheet, and the punched sheet falls directly into the blanking stacking bin 181. The working process of the spiral floating grinding mechanism: The blank falls horizontally into the blanking stacking bin 181. Guided by gravity and the spiral guide groove 182, the blank is forced to slowly rotate (about 10-30 rpm) during the fall. The circumferentially distributed floating grinding blocks 188 are continuously in contact with the outer edge of the rotating blank under the push of the fourth floating spring 189, achieving 360° deburring and chamfering without dead angles. At the same time, the air pump 183 is started to inject air into the air intake channel 184. The air enters the spiral guide groove 182 along the air intake channel 184, spirals upward to carry away the grinding debris and frictional heat, and flows out from the air outlet gap 185. This has the function of keeping the blank temperature always below 60°C and preventing the silicon steel sheet from annealing. Finally, the blanks are neatly stacked to the bottom of the blanking stacking bin 181 and can be taken out from the discharge port 187 of the base 186.

[0026] like Figure 1 - Figure 4 , Figure 8 and Figure 15As shown, a servo motor rotor lamination forming equipment further includes: a first station 121 with a base plate surface having punches corresponding to a first punch head 152; a second station 131 with a base plate surface having punches corresponding to a second punch head 162; and a third station 141 with a base plate surface having punches corresponding to a third punch head 172. Guide rods are provided between the top and bottom plates of the first station 121, the second station 131, and the third station 141. A first sliding bracket 127 connecting to a first mounting plate 125 is slidably mounted on the guide rod of the first station 121; a second sliding bracket 137 connecting to a second mounting plate 135 is slidably mounted on the guide rod of the second station 131; and a third sliding bracket 147 connecting to a third mounting plate 145 is slidably mounted on the guide rod of the third station 141.

[0027] In the above embodiments, it should be noted that the first sliding bracket 127 has the function of restricting the vertical movement of the first punch head 152, and similarly the second sliding bracket 137 has the function of restricting the vertical movement of the second punch head 162, and the third sliding bracket 147 has the function of restricting the vertical movement of the third punch head 172, thus maintaining the consistency of punching.

[0028] like Figure 1 - Figure 3 As shown, a servo motor rotor lamination processing and forming equipment also includes a power supply 114 and a central control module 115 installed in the lower frame 112. Dustproof partitions are provided on both sides of the power supply 114 and the central control module 115. A first central control screen 122 is installed on the top of the first station 121, a second central control screen 132 is installed on the top of the second station 131, and a third central control screen 142 is installed on the top of the third station 141.

[0029] In the above embodiments, it should be noted that the central control module 115 is equipped with a high-performance industrial-grade multi-axis motion control core, a real-time process database, and an intelligent adaptive algorithm engine. The following key functional units are integrated within this module: (1) Multi-axis synchronous motion controller: Built-in high-precision interpolation algorithm, which can coordinate the motion trajectory of the first, second and third servo electric drive seats at the same time with microsecond response speed. It is responsible for the electronic cam curve planning of the "stamping-deburring" compound action, ensuring that the three drive axes maintain strict phase synchronization or perform attitude fine adjustment (such as tilt compensation) as needed during the downward stamping and upward reset of the punch, and preventing off-center load. (2) In-situ deburring intelligent decision-making system: equipped with a dedicated pressure-displacement closed-loop control algorithm, it collects load feedback in real time during the stamping process and automatically calculates the optimal deburring force point and stroke amount; (3) Distributed human-machine interaction communication gateway: It serves as a data hub and establishes bidirectional communication with the first, second, and third central control screens respectively through a high-speed industrial bus (such as EtherCAT or Profinet); it is responsible for distributing the real-time status (speed, torque, temperature, fault code) of each workstation to the corresponding screen for display, and receiving operation instructions (such as parameter modification, single-step debugging, emergency stop reset) from each screen, so as to realize "centralized control and distributed display"; The dustproof partitions set on both sides of the power supply 114 and the central control module 115 form an independent clean protective chamber. This design can effectively prevent dust from entering the core electrical area. The first central control screen 122, the second central control screen 132, and the third central control screen 142 are respectively installed on the top of the first workstation 121, the second workstation 131, and the third workstation 141, forming a distributed monitoring system of "one screen per workstation". Each screen can independently display specific process data of the corresponding workstation. Operators or maintenance personnel can directly view the real-time operating parameters of any workstation without having to travel back and forth between the two ends of the equipment or rely on a single central control console, which greatly improves debugging efficiency and fault response speed.

[0030] The usage process of this invention is as follows: Those skilled in the art hang coiled silicon steel sheets on a hydraulic uncoiler. The material passes through a multi-roller leveler, enters a servo roller feeder, and is precisely fed into the first station 121. When the silicon steel sheet is fed into the first station 121, the first servo electric drive base 123 controls the first punch rod 124 to drive the first mounting plate 125 and the connected first punching head 152 downwards. The first punching head 152 punches holes in the silicon steel sheet. The moment the first elastic sleeve 153 penetrates the silicon steel sheet, the first servo air injection module 191 is activated, pushing the air in the first air chamber 192 into the first punch rod 124 along the first air injection pipe 193. 24. In the lower air chamber, the rising air pressure pushes the first pneumatic rod 128, which in turn moves the first pressing head 154 downwards, forcing the first elastic sleeve 153 to expand radially and uniformly. The upward friction force is used to unidirectionally scrape and grind the hole wall. When the silicon steel sheet is fed into the second station 131, the second servo drive base 133 controls the second punch rod 134 to move the second mounting plate 135 and the connected second punch head 162 and third punch head 172 downwards. The second punch head 162 and third punch head 172 punch holes in the silicon steel sheet. The moment the second elastic sleeve 163 and third elastic sleeve 173 penetrate the silicon steel sheet, the second servo drive base 133 is activated. The air injection module 194 pushes air from the second air chamber 195 into the lower air chamber of the second punch 134 via the second air injection pipe 196. The increased air pressure in the chamber pushes the second pneumatic rod 138, which in turn moves the second and third pressing heads 164 and 174 downwards, forcing the second and third elastic sleeves 163 and 173 to expand radially and uniformly. This upward friction force is used to perform unidirectional scraping and grinding on the hole wall. When the silicon steel sheet is fed into the third station 141, the third servo electric drive base 143 controls the third punch 144 to move the third mounting plate 145 and the connected cutting head 146 downwards. The cutting head 146 cuts the silicon steel sheet. After being punched, the blanks fall directly into the blanking stacking bin 181. Guided by gravity and the spiral guide groove 182, the blanks are forced to slowly rotate during the fall. The circumferentially distributed floating grinding blocks 188, pushed by the fourth floating spring 189, continuously contact the outer edge of the rotating blanks, achieving 360° deburring and chamfering without dead angles. At the same time, the air pump 183 is started to inject air into the air intake channel 184. The air enters the spiral guide groove 182 along the air intake channel 184, spiraling upward to carry away the grinding debris and frictional heat. Finally, the blanks are neatly stacked to the bottom of the blanking stacking bin 181 and can be taken out from the discharge port 187 of the base 186.

[0031] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
